My invention relates to improvementsin foun- The instant invention isdesigned with the primary object in view of providing in afountain inkWell, supplied by an inverted bottle of ink, for utilizing a capped inkbottle in theV wellas a 'source of ink supply and for opening up thebottle by loosening the cap after the bottle has been placed in invertedposition in said Well.

Another object is to provide for accomplishing the above by means ofsimple form rand inexpensive construction so that the ink Well may bemanufactured, together with the ink bottle and cap, at a comparativelylow cost. To the accomplishment of the above, and'ancillary objects,presently appearing, a preferred embodiment of my invention has beenillustrated Ain the accompanying drawings, set forth in detail 'in thesucceeding-description, and defined in the claims appended hereto.

In said drawings:

4 clams. (C1. 12o-:59)

Referring to the drawings by'numerals, the 'type of fountain ink wellillustrated, and with which my improvements are especially concerned,comprises a flat bottomed body I which, as shown, is of generally ovalform in plan with a substantially cylindrical, open top, ink bottlecompartment 2 therein having a pen ller bowl 3 at 4one side thereof Withwhich said compartment 2 communicates. The body I, as shown, is fittedin and seated in a similarly shaped base 4 having an edge Abinder 5.v` Aplate 6 on the top I of the filler boWl'3 is provided with'a penrest 8depending through vsaid top 'I for supporting a pen 9 with the penpointy IIlspaced'from the bottom of Vsaid bowl. A cap-type cover I Ifitted on the body I, overthe ink bottle compartment 2, closes saideompartmenti Y According to thefinstant invention, the bottom l2 of thebody I is provided with'an annular, relatively small, bottle holder I3,of sleeve-like form, vupstanding therefrom in theaxis of the ink lbottlecompartment 2 and internallyitapered downwardly to said bottom I2.Within the bottle holder I3, said bottom I2 is stepped down to form anannular, raised, internal bottom shoulder I4 'in said holder. Adiametrical rib I5 is formed on said bottom I2, inside vsaid holderI3,'and Whi-ch extends from side to side of said'shoulder I4leveltherewith. A pair of aligned grooves lIISl are formed in said bottom I2,inside said'holder I3, `and which extend radially'thereof upon oppositeside'sfof vsaid rib I5 at rightangles thereto. vA pair ofl longitudinal,diametrically opposite, vinternal ribs I1 extend in said holder I3 fromthe rim thereof tothe shoulder I4, and a pair 0f internal diametricallyoppositelongitudinal grooves I8 in 90 angular relation to said ribsIl. iAt the bottom of the ink bottle holder I3, an ink discharge port I9 isprovided in the side thereof vand which forms an 'ink level port intheusual manner. ,A pair of` pin-'hole air inlet ports 20 vare 4formed inthe side of said holder I3 atthe top of faid port I9 and upon oppositesides of the same `for"'aparticular purposepresently'seen.

VA closure cap 2l is provided for an ink bottle 22 having a sloping top23' and an externally .threaded neck, 24, .The closure cap 2| issubstantially ,frufs'to'fconical' in .'form to conform w'ithftheinternal taper of the inkfbottle'holder circumferential shoulder -25adapted to t down .wardly ontheshoulder I4. A pair of longitudinal,diametrically.opposite,'ribs 26 on the side of said `closure cap. v2I, tin the longitudinal grooves I8 in the ink bottle holder I3. A pair oflongitudinal, diametricallyf opposite, grooves 21 in the side of theclosure cap 2I,"in 90 angular relation to the ribs 26, t over thelongitudinal ribs I'I in said holder I3. A diametrical top groove 28 inthe closure cap 2I .ts over the rib I5 at the bottom of said holder I3,and a pair of aligned, radial, top ribs 29 on said closure cap 2|, inangular relation to the groove 28 and upon opposite sides thereof, fit'in the grooves I6 in said holder I-3. A discharge port 30 in the side ofthe closure cap 2 I, similar to the discharge port I 9, and adjacent tothe top of said cap, is adapted to register with the discharge port I9,and a pair of pin-hole air inlet ports 3l in the side of said closurecap 2|, similar to the pin-hole ports 20, are adapted to register withsaid ports 20. The closure cap 2| is provided with internal threads 32extending part-way down the same for screwing said cap onto the neck 24of the bottle 2I, and with the usual gasket 33.

As best shown in Figure 5, when the ink bottle 22 is placed in the inkbottle holder I3, in inverted position, with the closure cap 2| screwedtight on the neck 24, and the ribs and grooves.2li, 21 of said capintertted with the grooves I8 and ribs II of said holder, also thegroove 28 and ribs 29 of said cap interfitted .with therib I5 andgrooves I6 of said holder, the closure cap ZI is interlocked with saidholder I3 at the sides and bottom of said holder and said closure cap isalso interlocked with said holder I3 against turning therein and withVthe'ports3ll, 3I- of said cap registered, with the ports I9, 20 of saidholder. Now, by unscrewing the ink bottle 22 to raise the neck24 of thesame above the threads 32, said neck 24 `is elevated sufficiently sothat the rim thereof clears the ports 30, 3I in the closure cap 2|,-.andthe ink bottle 22 is thus opened for discharge of ink therefrom throughthe ports I9, 30 into the compartment 2 and wel-1 3, to the level ofthetops of the said ports I9, 3!! while the pinholeA ports 20, 3Iprovide for admitting air to said cap.2| and neck 24 so that the inkwill ow freely from the ink bottle 2|. By merely screwingk the inkbottle 22- tightly into the closure cap 2l, -said bottle maybe closed,at will, as desired, rand for removaland replacement purposes. Byvarying the height of the rim of the neck 24 fromV the tops of thedischarge ports I9, 30, the level of the inkin the compartment 2 andbowl 3 may be varied. Interlocking therclosure cap 2| with the bottom I2through the ribs I5, 29 and the grooves I6, 25 provides irregularcoengaging surfaces on said cap and bottom tending to prevent inkseeping in between said cap and bottom from causing the cap to adhere tothe bottom and thereby render removal of the cap dilicult. Y

The foregoing will, it is believed, sui'lce to impart a clearunderstanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible .of modificationwithoutY departing from the inventive concept, and right is hereinreserved .to such modicationsas fall within the scope of the l,appendedclaims.
